Introduction

Plants are the major source of food for humans. Plants get the required nutrients from soil so that they can fulfill their basic requirements and also grow. The substances required by a plant to grow are called essential elements. These elements are required by all plants, but some of them may not be present in sufficient quantities in natural soils

Carbon

Carbon is a macronutrient that plants need to produce glucose and other organic compounds. As such, it is an important component of photosynthesis. Carbon dioxide (CO2) is made during photosynthesis and released as a byproduct of respiration. Plants use this CO2 to fuel their growth, while animals breathe in oxygen and exhale CO2 back into the atmosphere–a cycle known as carbon exchange between plants and animals called “carbon cycling.”

When you eat food containing carbohydrates such as fruits or vegetables that contain large amounts of carbohydrates, your body breaks down these complex sugars into simple sugars through digestion before absorbing them into your bloodstream where they can be used for energy production or stored as fat if there’s not enough space left over after exercising!

Nitrogen

Nitrogen is an element that is required for the formation of amino acids, proteins and nucleic acids. It also plays an important role in chlorophyll synthesis. Nitrogen is present in proteins, nucleic acids and chlorophyll.

Phosphorus

Phosphorus is an important element for plants to grow and develop. It’s a macronutrient, meaning it’s needed in large amounts by plants. Phosphorus plays an important role in photosynthesis, cell growth and division, respiration (the release of energy from food), and the production of seeds and fruit.

Phosphorus can be found in various forms: as phosphate ions (PO4) or phosphates; combined with other elements such as calcium or magnesium; or attached to organic compounds such as sugars (carbohydrates).

The soils where you grow your vegetables contain phosphorus which will be absorbed by the roots when they reach down into this layer of dirt called “soil” where most nutrients are stored!

Potassium

Potassium is an element that is essential for plant growth. It is also a nutrient that is required by humans, and it’s important for the development of roots, stems, and leaves.

Sulfur

Sulfur is an essential mineral that is needed for the formation of cysteine, an amino acid. It’s also used in the formation of keratin, which is found in hair and nails.

Calcium

Calcium is a mineral that’s important for cell division and the formation of new cells. It’s also required for bone development and maintenance, blood clotting and nerve conduction. Calcium can be found in milk, green vegetables (such as broccoli), some fruits (like oranges)

Takeaway:

The nutrients are the substances that plants need to grow and develop. They include:

• nitrogen (N)
• phosphorus (P)
• potassium (K)

The role of these nutrients is to make sure that your garden grows strong and healthy, so you can enjoy delicious fruits, vegetables, and herbs all summer long!

The takeaway from this article is that plants need a wide range of nutrients to grow and produce food. The four main ones are carbon, nitrogen, phosphorus and potassium. Plants also need calcium and sulfur which are found in smaller amounts but still important for healthy growth.
